HYDRAULIC AIR-COMPRESSOR.

SPECIFICATION forming part of Letters Patent No. 415,931, dated November26, 1889.

Application filed February 21, 1889. Serial No. 300,699. (No model.)

To all whom t may concern.-

Be it known that We, JOSEPH WEYAND, of Guttenburg, in the county ofHudson and State of New Jersey, and WILLIAM LANG, of

the city, county, and State of New York, have invented a new andImproved Hydraulic Air Compressor, of which the following is a Jfull,clear, and exact description.

Ourinvention relates to hydraulic air-com` Io pressors constructed towork automatically, and especially to that class of compressors employedto supply and maintain a predetermined amount of air-pressure uponliquids contained in casks or tanks stored, for in- I 5 stance, in thecellar of a building, to force such liquid through suitabledischarge-pipes to the ,tioor above, in order that the liquid thusraised may be conveniently drawn when and as desired through a faucetlocated upon the said ioors.

The object of the invention is to provide an apparatus which shallpossess superior advantages in point of simplicity, durability, andgeneral etficiencyover any similar appa- 2 5 ratus or device nowemployed for the same purpose.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter more fully set 3o forth, andpointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters and figures of referenceindicate corresponding parts in all the 3 5 views.

Figure 1 is a central vertical section through the apparatus,illustrating the parts as in position to exert pressure. Fig. 2 isasimilar section looking in an opposite direction, illus- 4o trating theparts as in position to relie-ve the pressure. Fig. 3 is a horizontalsection on line x of Fig. 1 looking downward, and Fig. 4l is a similarsection on line I/ Ii] ot` Fig. 2 looking upward.

In carrying out the invention the base A,

which is cast or otherwise formed of any suitable metal, is preferablyshaped to have a circular section 10, provided with a central circularcavity 11, and an essentially rectan- 5o guiar section 12, havingelbow-tubes 13 and 14, integral with the under side, closed atthe innerend. The tubel 13, which is a waterinlet tube, extends horizont-allyparallel with one side edge of the base-section 12, and preferablytransversely to an abutment with the longitudinal member of theoppositeparallel tube 14, which latter tube constitutes thewater-outlet, and the transverse member of the outlet-tube 14: ispreferably locatedbetween the base depression 11 and the corre- 6osponding member ot the inlet-tube-ordinarily near the latter.

Upon the upper face of the base-section 12 a iiexible washer l5 issecured by a plate 16, bearing thereon, which plate is screwed orotherwise detachably secured to the base, as best illustrated in Fig. 3.

In the washer 15 and the base A a preferably round opening 18 isproduced, leading directly into the transverse member 'of the 7oinlet-tube 13, which opening is adapted toreceive a vertically-boredboss 19 upon the under face ot' the plate 16, the bore extending throughthe plate and the boss being of sufi icient length to project abouthalf-way into the said tube 13, as best shown in Figs. 1 and 2. The wallof the lower end of the bore in the boss 19, which constitutes avalve-opening 20, is concaved, as best shown in at a in Fig. 1, to forma seat for a ball-valve 21. A 8o preferably larger and similar opening22 is made in the plate, washer, and base, leading into the transversemember of the outlet-tube 14, which opening is capable of being closedat the top by a disk-valve 23. The ball-valve 8 5 21 is provided with astem 24, loosely carried up through the valve-opening 20, and pivotallysecured in any approved manner to a lever 25, fulcrumed at one end upona post projected upward from the rear end of the 9c plate 16, and thedisk-valve 23 is also provided with a stem, which stein is rigidlyattached to the said lever. The valve-liever 25 extends longitudinallyover the plate 16 between guide-lugs 255L at the inner end of the plateand downward in a curved line within the base-cavity 11, terminatingover the center of the latter.

Upon the base A a perpendicular casing or shell B is bolted or Otherwisesecured, the Ioo said shell consisting of' an essentially-conicalsection 26 and a rectangular section 27, the side and end walls whereofare preferably inclined upward. The rectangular section eX- tends overthe conical section at the top to a point at or near the center, asshown in Figs.

Y section, as shown in Figs. 1 and 2, in which it will be observed thatthe greater portion of the rod between the ends is of larger diameterthan the said ends, whereby an upper and a lower shoulder 31 and 32 areformed.

Two hemispherical iioats 33 and 34 are held to slide upon the rod E30.,The lower lioat is limited in its'upward movement by the lower shoulder32, which it cannot pass. The upper float, however, is free to riseupward until it contacts with the inner upper surface of the conicalsurface of the shell, as shown in Fig.l 2. The contour of the shell atthis point is such as to neatly receive the upper float.

A nipple 35, having an eXteriorly-threaded fianged base, is formedintegral with the up- .per surface of' the cover-plate at or near theouter end, which nipple is covered by a flexible jacket 36, providedwith a slit at the top over the bore of' the nipple, as best shown inFig. 1. The jacket 36 is surrounded by a cap 37, having' an integraloutlet-tube 38, which cap is held in position by a lock-nut 39, swiveledupon the nipple and screwed upon the fiange of the same. A channel 40intersects thebore of the nipple, which channel extends longitudinallyrearward and downward through the bottom of the cover-plate 2S. A secondchannel 4l is produced in the front end of the cover-plate, affordingdirect communication with the interior of the shell B and the atmospheresurrounding the same.

The inner mouths of the channels 40 and 41 are controlled by disk-valves42 and 43, secured to an arm 44, fulcrumed near the outer end beneaththe cover-plate, the inner end of said arm being` slotted to receive theupper end of' the .float-rod capable of being acted upon by the shoulder31 of said rod. The valves 42 and 43 are located one at each side of thefulcrum-point of the arm 44, whereby when one channel-40, forinstanceisclosed the other channel 41 will be open.

the water entering through the inlet-tube 13 passes up through thevalve-opening 20 into the interior of the shell, whereupon the twofloats 33 and 34 are elevated, thereby creating an air-pressure withinthe shell, which, bearing downward upon the disk-valve 23, suffices toretain the same in a closed position. The lower tioat 34 rises onlyuntil it strikes the shoulder 32 of the rod 30, but the upper float 33continues to rise with the incoming water, and the air forced out fromthe shell by the entrance of the water finds an escape throughthechannel 40, which is open, as shown in Fig. 1; from thence throughthe nipple and out through the slit iu the jacket into the cap 37, andfrom the cap the compressed air finds an exit through the outlet-tube38,

lwhich tube is in communication with a barrel or cask containing thebeer or other iiuid. lVhen the upper iioat 34 is carried bythe water tothe position illustrated in Fig. 2- namely in contact with the upperinner surface of the conical section of the shell-the inner end of thearm 44, carrying the valves 42 and 33, is elevated sufficiently to closethe mouth of the channel 40 and open the inner mouth of the outerchannel 41. Through this channel the compressed air not needed in themanipulation of the fluid escapes, and as the air escapes pressure isremoved from the disk-valve 23, and the lower iioat, bearing upwardagainst the shoulder 32, raises the rod 30, thereby causing theball-valve` 21 to close the inlet-opening 20, which movement also raisesthe disk-valve 23, whereupon the water finds a speedy and free exitthrough the outlet-tube 14. As the level of the water nears the base ofthe shell the upper float finds a seat upon the lower float, and as thewater leaves the said upper float the weight of the latter causes thelower iioat to bear down a slight distance in the direction of theValvelever, the length o of the lower reduction of the iioat-rod beingso calculated that when the lower fioat is in this position the uppersurface will be removed some distance from the lower rod-shoulder 32. Inthe further op` eration, when the level of the water practically reachesthe level of the base, the combined weight of the floats is such thatthey will drop heavily downward and force the free end of the leverinstantly deep in the cavity 11, whereby the outlet-valve is closed andthe inlet-valve opened. The movement of the lever is so precipitated bythe action of the incoming water as soon as the ball-valve is unseatedin the slightest degree that the sudden violent downward movement of theiioats and lever creates quite a loud report.

The cavity 11 is always more or less filled with water, consequently thefloats rebound somewhat after striking the same, but the distancebetween the lower float and the shoulder is such that even at thegreatest rebound the two will notcontact; thus the lever remainspassive. Any well-known or approved forrn of regulator may be employedin TOO IIO

connection with the compressor above described.

Having thus described our invention, we claim as new and desire tosecure by Letters Patentl. The combination, with a shell having waterinlet and outlet openings, a lever pivoted within the shell, two valvescontrolling said openings and connected with said lever, and a verticalrod connected at its lower end with the said lever and provided withvertically-sliding` floats, the lower float having a limited upwardmovement on the rod to raise it, of air delivery and waste channels inthe upper end of the shell, alever provided with valves for bothchannels and extendinginto the path of the upper float, substantially asset forth.
